Script can't handle large number of user certificates

[jtrott]

I have a user (used as the service account for NDES) that currently has 1191 user certificates in the Published Certificates tab.
Here's the sanitised output of running your script:

PS C:\WINDOWS\system32> Get-ADUserCertificate -searchtype SamAccountNameOrCN -searchentry "svc_ndes"
